What makes a tuntable sounds warmer?


Dear all,
I replaced my 8 years old nottingham horizon with a new tuntable which priced a bit more than double.
All components remain the same incl. tonearm and cartridge (ortofon as212 and delos which both clocked about 150 hours). But after about 50 hours of playing, it sounds much warmer and lose details almost sounds like there is a towel on my speakers. I have experimented all settings on my turntable set but still resulting the same.

I Also check the speed but it's good at 33.3 and 45 rpm.

I think the horizon sounds better :(

What makes a turntable sounds warmer? It has dc power supply, is it due to power supply? How to make it sounds less warm?

Thanks a lot in advance for any advice

do you run the same loading for both cartridges. the effect you state sounds like when you run a MM cartridge that needs 47kohm into a MC input with 100ohm loading. I know my delos sounds best at 100 ohm, but my clearaudio beta aurum needs 47kohm or it sounds like you state, a towel placed over the speaker
